This afternoon I went mountain biking with Brent and Jesi. Brent just got new hydraulic disk brakes. He also put new shifters on.
Including going to Brent’s house, the ride was around 18 or 19 miles. It was a long slow grind but I feel like I’m finally getting my cycling legs back.
On Saturday Jesi and I ventured up the Angeles Forest Crest Highway to go hiking on a nice little trail and to see Mount Wilson Observatory. At the trail head we loaded up our water bottles and camelback before descending down into the canyon. The trail was partially in the cool shade and partially exposed along bright white granite outcroppings. I don’t think I’ve ever been on a hike with so many people before. We couldn’t walk more than a minute or two without running into another group. That’s the price you pay for hiking within easy driving distance of Los Angeles.
Gearing up at the parking lot. This is the highest lot and what is used when the lower three lots are full. Yes, there were a whole bunch of people hiking the waterfall trail!
Even in a supposed wilderness area they have power lines in California.
Looking down the canyon. We hiked down it a mile or two and lost maybe 1000 feet of elevation.
The waterfall at the bottom of the trail. There were other trails that went further into the “back country” of the mountains. We decided to turn around so that we could get to the observatory before it closed to visitors for the day.

The top of Mount Wilson is also used for a whole menagerie of radio and TV antennas. One must wonder what sort of radiation those antennas are putting out.
Solar observatories peaking over the trees.
The 150 foot tall solar observatory built about 100 years ago. The external structure is completely detached from a hidden internal structure. This allows the outside to sway and move in the wind while holding the inside completely stationary so that there is no deviation in the mirror adjustments.
One of six small telescope installations that are ganged together using a complex system of mirrors on tracks. This allows the six small telescopes to become one HUGE telescope for the purposes of whatever these telescopes are imaging. This system was installed fairly recently.
The 60 inch telescope. At one time it was the largest telescope in the world. Now it can be rented out by the public for star parties and amateur research. You and up to 25 of your closest friends can rent it out for a whole night for about $1500.
Walking in the direction of the 100 inch telescope.
The 100 inch telescope. This became the biggest telescope in the world when it was completed around 1918. It’s still a big telescope by modern standards.
Looking at the telescope inside the dome. It is aligned vertically to create the minimal amount of stress on the delicate mirrors.

The 100 inch telescope is designed with multiple layers of covering. Each has an air gap between it and the next layer. This helps keep the mirrors inside cold and regulates the temperature without the need for air conditioning.

The Los Angeles basin. Such a huge place full of way too many people!

Last weekend Jesi and I drove from Los Angeles to Monterey, Ca for some SCUBA diving. Jesi only had a few dives to finish to complete her divemaster training. I agreed to get her through her last dives to certification.
We drove six hours to make it to Trista’s apartment in Monterey a little before 1am. A few hours of sleep later, we were up and on our way to rent some gear and hit the water. Diving waits for no man!
On Saturday night Trista joined us for an awesome night dive. I didn’t think to bring my camera which was rather unfortunate. We saw at least six baby octopi walking along the bottom hunting for food. Some of them didn’t seem to mind us looking at them. One or two were a little mad. It was so neat seeing the babies walk along the bottom foraging for food!
Sunday saw us complete several more dives before we turned our car south and headed home along the coastal highway. South of Big Sur we just made it through a police roadblock before a lifeflight helicopter landed and shut down the highway. Without traffic behind us it turned into a very pleasant drive back to LA.
